Bug ID: 90213
Summary: glDrawPixels with GL_COLOR_INDEX never returns.
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
Assignee: mesa-dev@lists.freedesktop.org
Reporter: juhapekka.heikk...@gmail.com
QA Contact: mesa-dev@lists.freedesktop.org
When I run glDrawPixels(width, height, GL_COLOR_INDEX, GL_UNSIGNED_BYTE, data)
code execution never return.
Commit 84eb402c01962e3ff4b70c9948c85a61ed81678f changed the path so we end up
in _mesa_format_from_format_and_type at src/mesa/main/glformats.c:2682 which
does not seem to know anything about GL_COLOR_INDEX. On release build this
function should return a value but doesn't and gets confused, on debug build I
get assert _mesa_format_from_format_and_type: Assertion `!"Unsupported format"'
failed.
I made minimalistic test for this, one can get it from here
https://github.com/juhapekka/CI_test.git
There seems also exist test in Piglit which does similar and halts Piglit run.
Piglit test is gl-1.0-drawpixels-color-index
